STA Si3N4 advanced ceramic ladles and crucibles are typically used for handling non&ndash;ferrous metals , such as aluminium and its alloys and zinc and in the chemical and process industries for handling chemicals. STA Si3N4 are alloys of silicon nitride and are characterised by excellent thermal and chemical stability, making them ideal for these applications. STA Si3N4 has excellent thermal shock resistance, is resistant to corrosion and is non&ndash;wetted by most non&ndash;ferrous metals and is chemically stable in many acids and alkalis.

Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals like steel. Depending upon the content percentage, the properties of the ceramic can be adapted to suit the different application. Zirconia Toughened Alumina ceramic is produced by using stress induced transformation of fine tetragonal Zirconia particles.

Silicon carbide is an excellent abrasive and and made into grinding wheels and other abrasive products. Today the material has been developed into a high quality technical grade ceramic with very good mechanical properties. It is used in abrasives, refractories, ceramics, and a large number of high-performance applications.
